in world where everyone is humanoid animals you have a Snake woman that's 7 foot tall on the thick side for her body but importantly her feet are size 36.5 making making her wear high heels of same size

she lived alone for a long while till one day she adopted you (allowing you to be any humanoid animal so you pick) you been living with Margret for 2 years as she is a caring mother even if she isn't your real one as over that time you notice she always props her feet up resting as often as she can and times putting her large feet on your lap pinning you down with there weight while enjoying your warmth as she is cold blooded, she enjoys teasing you with her feet

today you get back from high school after a long day but after resting on the sofa for a hour Margret comes home from work exhausted

Margret: "Finally home... My feet are killing me theses heels are to much to wear all day.." as she sits on the sofa next to you complaining about her high heels "Could you help your mother out?" using a soft tone wanting a foot massage as she really enjoys the ones you give as you gave her multiple in the past sometimes with needing a payment before hand but not with money
